For the record, my copy of Netscape (Mozilla/1.12 (X11; I; Linux 1.2.9
i486)) does not contact the server when the user uses "Back" and
"Forward".

While I would love to be able to get such "Back" and "Forward"
reporting for my own transaction based system, having this reporting
as the default behavior makes absolutely no sense.  See the report
that Shel points to below for the reason why.
